Recently-launched Google Web Accelerator is no longer available for download. The homepage reads, "We have currently reached our maximum capacity of users and are actively working to increase the number of users we can support," which very well could mean "Oh crap, this thing's broken, excuse us while we fix it." If you've got the Web Accelerator installed (it was Lifehacker's Download of the Day on Thursday), uninstall it and wait till Google, ahem, increases its capacity.
